简要总结
Aim of the study was to evaluate clinically and by non-invasive instrumental evaluations the "revitalizing" activity of a face cream applied twice a day, morning and evening, for an uninterrupted period of 8 weeks, by healthy female volunteers aged 45-55 years with face ritidosis and women aged 55-65 years not habitual user of antiage-creams.
The study foresaw the comparison within subjects of the study product versus placebo (half face method).
It was also aim of this study to evaluate products efficacy and cosmetic acceptability by the volunteers and tolerance both by investigator and volunteers.

结局指标
主要结局
Profilometry: change from baseline (T4 and T8 vs. T0)
时间窗: T0 (basal conditions), T4 and T8 (after 4 and 8 week-treatment)
A picture of crow's feet area was taken thanks to Primos compact portable device (GFMesstechnik); a software able to elaborate 3D representations of skin wrinkles as well as to measure skin principal profilometric parameters in vivo or on skin replicas, according to the law DIN EN ISO 4228; moreover the software compares directly the different images obtained at the times foresee by the protocol (T0, T4 and T8).The portable probe assures a constant distance from the skin as well as a fixed illumination angle of incidence; in this way is possible to acquire standardized and reproducible images.
次要结局
- Optical colorimetry: change from baseline (T4 and T8 vs. T0)(T0 (basal condition), T4 and T8 (after 4 and 8 week-treatment))
- Skin electrical capacitance: change from baseline (T4 and T8 vs. T0)(T0 (basal condition), T4 and T8 (after 4 and 8 week-treatment))
- Photographic documentation:(T0 (basal condition), T4 and T8 (after 4 and 8 week-treatment))
- Clinical evaluations: change from baseline (T4 and T8 vs. T0)(T0 (basal conditions), T4 and T8 (after 4 and 8 week-treatment))
- Skin plastoelasticity: change from baseline (T4 and T8 vs. T0)(T0 (basal condition), T4 and T8 (after 4 and 8 week-treatment))
- Spectophotometry: change from baseline (T4 and T8 vs. T0)(T0 (basal condition), T4 and T8 (after 4 and 8 week-treatment))
- Tape stripping:(T0 (basal conditions), T4 and T8 (after 4 and 8 week-treatment))
